Because Delaware does not have its own approved occupational safety and health plan, the federal OSHA and its worker right-to-know standards are the governing law of the state in all private sector workplaces. There is no state or federal safety and health law for government offices and operations in Delaware. Check with municipal codes for any local ordinances. There is additional information and a detailed discussion of the federal regulations.
Delaware does have a Hazardous Chemical Information Act (DE Code Tit. 16 Sec. 2401et seq.) in its legal code, but it is not implemented or enforced by any state agency.
